Provided is a floating type solar power generation equipment stage (10) device, comprising a carrier (1) and a plurality of floating collars (2). The carrier (1) is made of a hard material, and has an outer frame portion (11) in a horizontal direction and a link bar (12) disposed at the center of the outer frame portion (11). Further, the outer frame portion (11) is vertically disposed with a plurality of straight strip-shaped bonding columns (13) downwards, and an adjustment portion (14) for adjusting the buoyancy of the stage is disposed on the carrier (1). Each of the plurality of floating collars (2) is a buoyant hollow ring, and its center has a sleeve hole (114) into which the bonding column (13) can be inserted so that the floating collars (2) can be arranged vertically up and down on the bonding column (13), and the stage (10) can be floated on the water with vertical buoyancy. Moreover, there is a water flow spacing between the vertically arranged floating collars (2), thereby having better floating stability and maintaining ecological functions.
